NAME AND OPERATION OF PARTS

Before use, pull out the insulating sheet from the battery compartment, as shown in the illustration below. If the sheet is torn off and left inside the compartment, open the battery hatch by referring to “BATTERY CHANGE” below, and remove the remainder of the sheet completely. Otherwise, the tuner will not be turned on.

Note: The battery included with the tuner is a monitor battery, and the battery life may be shorter than the specified period.

Power button

With each press, the tuner stands by for “CLIP” and “MIC” input, and is turned off in order.

●CLIP input method:

The vibration sensor senses the vibrations generated when the instrument gives out a note, and tuning is made using them. This input method is convenient for the tuning in noisy environments or in a situation where other instruments are played nearby.

●MIC input method:

Tuning is made using the note of the instrument input through the built-in microphone .

Mode button

Use the button to select the tuning mode from auto ( ), manual ( ) and sound ( ).

Auto mode : By playing a note, the tuner automatically identifies and indicates the note having the pitch closest to it. It also indicates that the pitch of the input note is lower or higher than that of the indicated note.

Manual mode : Set the note you wish to tune, and then, play a note. The tuner indicates that the pitch of the input note is lower or higher than that of the note you have set.

Sound mode : The tuner gives out the note you have set. Tune the instrument on the basis of the reference note the tuner produces.

Pitch button

Use the button to set the reference pitch (frequency of A4).

By pressing the button, an LED of reference pitch LED display flashes for a certain period of time to show the current pitch setting. With each press of the button while the LED is flashing, the reference pitch increases by 1 Hz. It increases continuously if the button is kept pressed.

*If the tuner is left untouched with an LED flashing, the reference pitch indicated by the LED is automatically registered in a certain period of time.

●Settable range:

415 Hz ⇒ 438 Hz ⇒ 439 Hz ⇒ • • • • • ⇒ 444 Hz ⇒ 445 Hz

⇒

(at 1 Hz steps from 438 to 445 Hz)

Note button

Use the button to set the note you wish to tune.

With each press, the note changes over at one-semitone step. It changes continuously by keeping the button pressed.

*In the auto mode, the note button is disabled as the tuner automatically identifies and indicates the input note.

●Settable range:

Manual mode	:	C ~ B (12 notes)
Sound mode	:	C4 ~ B4 (12 notes)

: By playing a note, the tuner automatically identifies and indicates the note having the pitch closest to it. (The difference in octave is not indicated.)

Manual/sound mode: The note you have set is indicated. (The octave cannot be set.)

Input method indication

The input method you have selected is indicated.

Mode indication

: Auto mode : Manual mode : Sound mode

Tuning guide/ reference pitch LED display

In the auto and manual modes, the difference in pitch between the note indicated on the display and the note given by the instrument is indicated by the LED that lights up. (See the numeral on the right of the LED that lights up.) The LED display also indicates the reference pitch you have set. (See the numeral on the left of the LED that lights up.)

Built-in microphone

Use it to input a note directly from the instrument in the “MIC” input method. When the “CLIP” input method is selected, the built-in microphone is disabled.

Vibration sensor/built-in speaker

In the “CLIP” input method, it senses the vibration generated by the instrument. When the “MIC” input method is selected, the vibration sensor/built-in speaker is disabled. In sound mode, the reference note you have set is produced from the built-in speaker.

Clip

Attach the tuner to the instrument using it to sense the vibration it generates.

HOW TO TUNE THE INSTRUMENT

■Auto/manual mode

Play a note with the instrument, and tune it according to the note indication and the tuning guide .

1.Press the power button to select the “CLIP” or “MIC” input method. When the “CLIP” input method is selected, attach the tuner to the instrument using the clip .

2.Select the tuning mode. Press the mode button to set the tuning mode to the auto ( ) or manual ( ).

3.When the manual mode is selected, press the note button to set the note you wish to tune.

4.To change the reference pitch, press the pitch button to set the desired pitch.

5.Play the instrument to give a note. When the “MIC” input method is selected, bring the instrument close to the built-in microphone .

6.Tune the instrument until the LED at the center of the tuning guide lights up in green. In the auto mode, also check the input note with the note indication .

■Sound mode

The tuner gives out the note you wish to tune, and tune the instrument on the basis of the reference note the tuner produces.

1.Press the power button to select the “CLIP” or “MIC” input method. (The sound mode is available irrespective of the input method selected.)

2.Select the tuning mode.

Press the mode button to set the tuning mode to the sound ( ).

3.Press the note button to set the note you wish to tune.

4.To change the reference pitch, press the pitch button to set the desired pitch.

5.Tune the instrument on the basis of the reference note the tuner produces.

●Precautions on tuning

1.The tuner may pick up noise from the surrounding environment or the hum noise generated by electric appliances, and shows indications as if a note is played. This is not a malfunction, and the tuner operates properly when a note is played.

2.When the “MIC” input method is used, it is recommended that the tuning procedure be performed in a quiet environment for accurate tuning. Also, bring the instrument close to the tuner to register a note.

3.If you find it difficult to tune the instrument with the “CLIP” input method, re-attach the tuner in such a position to the instrument that the vibrations are transmitted to the tuner more clearly.

AUTO POWER-OFF FUNCTION

The tuner is equipped with an auto power-off function as described below to save the battery energy.

■Auto/manual mode

1.If none of the buttons , and is pressed, if no note is input in the

built-in microphone or if the vibration sensor senses no vibrations for approximately 10 seconds while the power is turned on, the liquid

crystal display becomes slightly dim. (Power save mode, Phase 1)

2.If the tuner is left untouched further for approximately five more minutes without sensing a note or vibrations, the liquid crystal display becomes

black, and the green LED at the center of the tuning guide starts flashing. (Power save mode, Phase 2)

3.If the tuner is left untouched further for approximately 15 more minutes without sensing a note or vibrations, the tuner is turned off automatically. (Auto power-off function)

■Sound mode

1.If none of the buttons , and is pressed for approximately 10 seconds while the power is turned on, the liquid crystal display becomes

slightly dim.

2.If the tuner is left untouched for approximately 5 more minutes, the tuner is turned off automatically. (Auto power-off function)
